    Diagonal matrix and its elements

    Whether zero can be there in the main (Principal) diagonal of a Diagonal matrix?

    Offshoot of the above question whether (square) null matrix can be called as a Diagonal matrix.

    Kindly guide me.

    with warm regards,

    Yes, there can be a 0 on the main diagonal of a diagonal matrix. That means that 0 is an eigenvalue, that the determinant of the matrix is 0, and that the matrix is not invertible.

    Yes, the 0 matrix can be considered a diagonal matrix- just not a very interesting one.
